人教版英语八下状语从句讲+练

八下状语从句:一个完整的句子修饰主句中的动词、形容词/副词或这个大句子等，充当状语的成分。

起副词作用的句子（故也叫副词性从句）。

根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。

状语从句一般由连词(从属连词)引导，也可由词组引导。

从句位于句首或句中时常用逗号与主句隔开，位于句尾时可以不用隔开。

一：时间状语从句在时间状语从句中，由状语从句表示主句动作发生的时间。

要点：时间状语从句，由以下连词引导：when（在…时）, as（当…时）, while（在…期间）, before（在…之前）, after（在...之后）, since （自从...以来）, not...until（直到…才）until/till(直到…时）等特殊引导词：the minute, the moment, the second,the day,every time，no sooner… than（一...就...）, hardly…when（一...就...）, as soon as(一…就…)。

在时间状语从句中，要注意时态一致。

一般情况下主句是将来时的时候，从句主要用一般现在时。

当含有否定意义的连接词如：no sooner…than，hardly…when作为引导词且位于句首时，从句要部分（半）倒装。

No sooner did I go to the park，than I saw him waiting for meHardly had we started when it began to rain.No sooner had I arrived home than it began to rain. 我一到家就开始下雨了。

Every time I listen to your advice, I get into trouble. 每当我听取你的建议时，我就会惹上麻烦。

二：原因状语从句由连词because, since, as引导, 也可由now that 等词引导。

常见的状语从句可分为：时间、条件、地点、原因、方式、让步、比较、结果、目的等从句，由不同的引导词引导。

考点一：时间状语从句引导词用法例句when when引导的时间状语从句中既可接延续性动词，也可接非延续性动词，多用一般过去时They were talking happily when I walked past the door.当我从门前走过，他们正在开心地聊天。

while while强调主句和从句动作同时发生，所引导的时间状语从句只能用延续性动词，多用进行时态。

My mother was cooking while I was doing my homework.当妈妈在做饭的时候，我在做作业。

not … until主句的谓语动词为非延续性动词，主句要用否定式，从句用肯定式。

The bus won’t start until everybody gets on.公共汽车直到每个人都上车才会发动。

since主句谓语动词一般用现在完成时，从句谓语动词一般用一般过去时。

Five yeas has passed since we saw each other last time.距离我们上次见面已经五年过去了。

before before 引导的从句表示主句的动作发生在从句动作之前。

We turned off the light before we left.我们在离开前关了灯。

after after 引导的从句表示主句的动作发生在从句动作之后。

He went to bed after he finished his work.他做完工作后就去睡觉了。

as soon as若主句为一般将来时，从句常用一般现在时表将来。

I will tell him the news as soon as I see him.我一看见他，就会告诉他这个消息。

He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory.(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。

(word完整版)初二英语时间状语从句讲解与练习

初二英语时间状语从句讲解与练习撰稿：胡欲晓审稿：牛新阁责编：白雪雁when, while 和 as 引导时间状语从句的用法这三个词的意思很简单，都有“当……时候”的意思。

但学生经常会问三个词的区别在哪儿，特别是在做选择题的时候。

别说是学生，就我个人而言，做这样的选择题要保证百分之百的正确也是不可能的。

现根据大量的实例和个人的思考，做一点小结，供大家参考。

一、when 的用法如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。

1. When he was a child he was always trying out new ideas.他小时候就常常试验一些新的设想。

2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。

3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。

5. He was on the point of leaving when someone knocked at the door.他正要走，这时有人敲门。

6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。

7. I had hardly[scarcely] closed my eyes when someone knocked at the door.我刚一闭上眼，就有人在敲门了。

根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B发生的时间点。

也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。
